If you have the receipt or empty box, you can find out. Also 2 litre prints of same 4 litre is also available. Never overfill or underfill CVT fluid.
If you can't find out what you poured in CVT, then just have it done again. You can find out which one to use by looking at CVT oil inlet bolt. It's written there TC or FE. IT WILL COST YOU BUT IT WILL SAVE YOU FROM BIG TROUBLE OF FENDING AND REPLACING THE WHOLE TRANSMISSION.
